“LIVE ROCKS” These are pieces of rock or fragments of dead coral (madreporites), that are bound together by calcareous rocks or various pieces of debris from invertebrates. They are sometimes removed from their natural setting and sold commercially. “Live rocks” harbor various organisms: bacteria, algae, sponges, small Coelenterates, and sometimes even small crustaceans, hidden […]
The small abdomen is tucked under the lower part of the body. Their pincers are particularly well developed. The larger specimens, which can be aggressive, must not be put into marine aquariums, as they can attack other invertebrates, and sometimes even fish. Pagurids These are better known as hermit crabs. Some tropical species can be […]
MOLLUSKS Few mollusks are found in aquariums, and they are not often available commercially. Among the gastropods, the cowries, well known to collectors of shells, can be kept in captivity. Some fish may nibble the “mantle”, the part of the animal’s body used outside the shell. Of course, in the event of any danger the […]
Coelenterates Urticant (stinging) Coelenterates must be kept apart from the more delicate species: a safety margin of 10-15 cm is often recommended. The madreporites and anemones are among the most urticant, and they must not be put alongside a leather coral from the Sarcophyton genus, for example. Other alternatives for a Coelenterates tank are algae […]
INVERTEBRATES The leather corals of the Sarcophyton genus will not tolerate being dose to Coelenterates highly prone to stinging. In their natural habitat, Coelenterates feed on animal plankton, but these are difficult to supply in an aquarium. example, is carrying out research in this field, using a 40 m3 tank containing […]
